To all whom t 71mg/ concern.'

Be 1t known that I JOHN J. Zorsin a 7 i subject of the Emperor of Austrla-lilungary,

residing et Greensburg, in the county oi:

lVestmcrela-nd and State oit Pennsylvania, have invented certain new and useful Iniprovements in 7aslung-Machines, oi which the Jfollowing is a specification.

The present invention relates to a machine tor washing cups, which is meter-ably used in conjunction with a machine ior washing plates, and similar utensils, and a machine for washing' knives, forks and the like, the whoie comliirising a complete wash ing machine, as is more iully described in my United States Patent No. 1,35 ,302. granted September 21.` 1920. The said Letters Patent cover what is therein described as the plate washing machine, while the present application is designed to cover the cup washing' machine as herein described, and is a division ci the above described Letters Patent.

For a clear understanding of the present washing machine, some reference will be made hereinafter in this specification, in a general way to the companion devices above mentioned, which taken together torni the complete washing machine.

The means employed to accomplish the object sought, namely the washing oi.' plates, bowls, cups. saucers and knives and forks, consist in a receptacle having therein a num bei' of rotating and reciprocating brushes, and a plunger adapted to create suction together with a means of rotating some of they dishes simultaneously with the operation ot the other features of the washing' machine.

The whole machine is constructed so that it may be readily cleaned after use, and adapted to be operated by a water motor, or other readily available means of power, and is also provided with its own supports 'for convenient household or hotel use.

These and other objects and desirable 'te-atures will bey brought out more fully hereiir zitter in this specification as the desi'fription proceeds.

In the accompanying drawings I have shown one complete example of the physical embodiment of my invention constructed ac-` cording to the best mode I have so far devised for the practical application of the principles of my invention.

For convenience of description I will designate the three mechanisms which together form the complete washing machine as ich lows. The knife washing machine l, in which the knives, forks, spoons and similar utensils are washed; the cup washing machine 2; and the plate washing machine 3, in which plates, saucers, bowls, and similar vessels are Washed. It will be observed that the knife and cup washing machines are in one compartment 4, while the plates are cleaned in another compartment 5.

The numeral. 6 indicates a box or receptacle preferably of wood or similar material having a bottom 7 and side walls 8, 9, 10, 11, and a cover 12 hinged at 13 to the rear Wall 10 and adapted to be secured at 14 to the front wall 8. A portion of the front wall 15 is hinged at 16 so that the same may be opened as shown by the dotted position 17. An inner partition wall 18 separates the compartments 4 and 5, and the box 6 is supview of a pordevice taken on line 11-11 of ported by the legs 19, 20, etc. The box is also provided With drain pipes 21, 22 having the Vfollowing parts.

Vout the `box 6 as shown.

connection with the compartments 5 and 4 respectively, and control valves 23, 24. Said drainage pipes form a junction and both exhaust into pipe 25, Which last is provided with a valve 26.

A main drive shaft 27 is positioned near the top of the box 6, and approximately in the center thereof. l

The said drive shaft 27 has bearings at 28, 29, 30, as shown in Fig. 11 of such design as will permit of shaft 27 being entirely removed from the box' 6, and a pulley 31 rigidly mounted thereon preferably with- The fixed pulley 31 is adapted to receive power from any suitable source of power (not shown). The drive shaft 27 has a number of bent portions 32, 33, 34, 35 which provide points of attachment for a number of connecting rods similar to rod 36 used to operate various parts of the washing devices.

The knife and cup washing compartment 4 has a removable frame 4() consisting of A horizontally dis- Y posed perforated board 41 hinged Vat 42vto a longitudinal strip 43, (see igs. 4, and 6) ;V two vertically disposed partitions 44, 45 rigidly attached to two end pieces 46,

Q47; a horizontally disposed piece 48 rigidly Vattached to the vertical partition 45 at 49,

and having aseries of openings 50, 51, etc.

adapted to receive the ordinary cups 52,

53, etc.; and a vertically disposed piece 54 whichV is rigidly attachedv to the horizontally l disposed piece 48. A perforated part 55 is 'hinged at' 56 to Vpart 57, the latter being Vrigidly attached toYV the. end piece 47 as shown iniFig.` 6. Thev part 57 also carries the plunger 58which is hinged at 59 thereto. Plunger 58 has a pivoted connection at 60 with a removable bolt therein adapted to engage thelower end of the connecting rod 36. The frame'40 also is provided with two Vside pieces 61, 62, and a longitudinal rear piece 63, all yrigidly attached to horizontal part 48. A horizontally disposed gear supporting part'64 is Vhinged at 65 tothe longitudinal rear lpiece 63, and carries-,a number'of shaftsrwith bevel gears thereon, as ,willbe described.

The main drive shaft 27vcarries rigidly mounted thereon a bevel gear 66 which meshes with the bevel gear-67 carried on the upper end of the vertical shaft 68. The Vlatter shaft 68 is supported near its upper Y end '.bya ihorizontally disposed support 69 having a bearing 70 therein, and attached at 71,ar to the rear wall '10 of the box 6 t Vafloresaid. The bearing70 is as shown in y Figs. 7 8 and 10. YThe free'end of the support'69 is curvedrasshown in Fig. 10, and

ftogetherf Vwith the complementary curved part 72 andthe hinge 71 forms the bearing 70 in which the vertical shaft 68 revolves. The part 72 is provided with a slot 73 and engages under the revoluble bent pin 74 mounted in the support 69. lt is evident that when the pin 74 is in the position shown in Fig. 7 that the vertical shaft 68 is securely held in the bearing 7U, and also that the said shaft 68 may be readily removed from the latter when required. y y

At its lower end shaft 68 is removably seated in a bearing 75 which last is rigidly attached to the gear support 64, and shaft 68 carries a bevel gear '76 which meshes into a series of bevel gears 77, 78, etc., on radially disposed shafts 79, 80, etc. The latter shafts 79, 80, etc. are supported in bearings at 8l, 82 on the gear supporting part 64, and carry bevel gears 83, 84, etc., which mesh into the bevel gears 85, 86, etc., on the upper ends of the vertical brush shafts 87, 88, etc. The shafts 87, 88 it will be observed are rotatably mounted in the gear supporting part 64, and are provided with bristles 89 substantially cylindrical in outline and adapted to approximately lit the interior of an ordinary cup. 1t is evident that when the drive shaft 27 is rcvolved the motion will be transmitted through the various gea and shafts to the brushes 89, revolving same within the cups supported in the horizontal part 48. lt is also apparent that the rotary motion oi' shaft 27 is changed to reciprocating motion in the connecting rod 36, and that the plunger 58 of the'knife washing mechanism is operated up and down as a result, thereby inducing a suction, through the holes 90 of the perforated part 55, and holes 91 of the perforated part 4l, when chamber v4 is pai'- tially filled with water, as will be explained more fully hereinafter. The frame 40 rests on the longitudinal supports 92, 93 attached to the front and rear walls 8 and l() of the box 6.

It is also to be notedV that when the connecting rod 36 is disconnected at 60, and vertical shaft 68 disconnected at 70 or otherwise from the bevel gears 77, 78, etc.. that the frame 40 and accompanying parts can then be entirely removed from the box 6. And it is further observed that the cleansing of the frame 40 can be readily accomplished due to the hinged connection of parts used at 42, 56, 59, etc. The purpostl of the perforations in the horizontally disposed parts 48 and 41 is to permit any of the heavier solids that may be washed from the cups, knives, forks, etc., to pass down through the perforations to the bottom portion 94 of the chamber 4'.

In connection with the vertical connecting rod 36 and vertical shaft 68, a specially constructed joint is used, as shown in large detail in theFigs. 7 to l0 of the drawings,

.llt

which shows the vertical shalt (33 of' the cup washing mechanism. The shatt (i3 is formed ot tivo separate parts 130, 131. llhe upper portion 13() as betore explained being` supported by horizontal support G9 in the bearing '70, and the lower portion 131 being-:rl attached slidably and pivotally to the upper portion 130 by means of tivo side splice plates 132, 133 and pins 13a, 135, 'which pass through said plates and the parts 130 and 131. )i plate 136 is rigidly attached to the upper part 130 and projects over the upper' end ot the lower part 131 at 137, but is not attached to the latter, ilorlning a rear support for the joint 138.

@n its face the upper part 130 has a slidable plate 139 pivotally connected at 1&1() to the same, and having a slot lll therein adapted to slidably engage under headed pin 111-2 lined in the part 131. lt is seen that when the pivoted plate 139 is parallel with the shalt G8 and in engaged position beneath the headed pin 142 that a rigid joint is made at 138, and also that when the plate 139 is reversed the part 131 can then taire a number oit' positions such as shown dotted at 1113, in which case bevel gear 7G is disengagged :trom bevel gears 7T, 73 ete. or part 131 can be made to assume the position indicated at 1114. The utility et this Afeature ot the shaft GS is at once apparent in connection with the removal et the 'trame 110 and accompanying` parts 'from the bei; 6. lt is readily understood that the same feature is applied to the connecting rod 3G for the same purpose. It will also be under stood that 'when the sha't't 27 is removed entirely from its bearings, by disengaging the connecting rod 36 from the plunger 58 at 60, and connecting rod 39 from shaft 122, the frame can be lifted bodily irom'the Washing machine chamber il, in which case the vertical shalt is removed from the bearing vT0; and that in this citent the specially constructed lioint 138 is unnecessary. It may be said however that the shalt 2i' is ordinarily removed for cleaning` purposes only, Whereas the joint 138 permits the cups, lrnives, itorlrs, ete., to be inserted in the Washing machine, and the portion 15 el' the front Wall 8 of the box is hinged at 1G to permit oit greater freedom oit movement in. this connection.

Operation el? the device is as follows. flhe cover 12 is thrown backward, connect ing,v rod 36 and shaft G3 are disconnected at their loiver extremities, broken at the joints 138 in each, and then placed in an inverted position similar to that indicated at 14e in Fig. 7, as nearly as the circumstances Will permit. The portion. 15 oit the liront ivall 8 oli the box is throivn open, the parts Gi, 58, are raised upward and the knives, forks and spoons, are placed in the knife washing mechanism 1, and the cups in the openings in the horizont-al part 11S. The shaft G8 is novv replaced in position in the bearing;v 75, and the connecting,1 rod 36 reconnected to the plunger 5S at point (3U, and the device is ready to be partly iilled with soap suds andhot Water. lt is to be noted in this connection. that the water level maintained in the chamber 11 is preferably lower than in chamber 5, and the division 'Wall 18 is designed to meet this condition. The portion 15 o' the liront 'Wall S ol the box is new closed, the cover 12 replaced and loclred at 1d and power from a water motor (not shown) or other source is applied to pulley 31, and shaitt 27 thereby op crates the brushes 3i' Within the cups, and plunger 58 reciproeates and by suction washes the knives, orlrs and spoons Within the chamber ot' the lrnil'e 'washing mechanism 1.

When thoroughly washed the dishes can be removed as readily as they were inserted in the device, the chamber ll drained by pipe 22, and the Washing; machine is ready l'or a repetition olf the operation when necessary.

rlhe Wishing machine can be brought into close relation with the ordinary sinh, a Water motor attached to the faucet, and connected by belt to pulley 31 thereby :furnishing the power to operate the device. After use the irashiiur machine can be removed bodily to any convenient place, and the same is :turnished with supporting; leps 19, 20, etc., for this purpose. ilny water that may spill over the top edges of the box G is caught by the l.gutters 145 termed in the bottom 7 oit' saine. Frein the above description it is seen that l have provided a device el utility :tor the purpose intended and above set forth.
